RAILWAY-SIGNAL.

SPECIFICATION forming part of Letters Patent No. 294,116, dated February 26, 1884.

Application iiled November 3, 1883. (No model.)

To all whom t may concern.'

Be it known that I, BERT BUYS, of Reese, in the county of Tnscola and State of Michigan, have invented new and useful Improvements in RailwaySignals; and I do hereby declare that the following is afull, clear, and exact description thereof, reference being had to the accompanying drawings, which form apart of this speciiication. y

This invention relates to an improvement in that class of railway-signals in which an arm moves at the same time as the signal, and carries a contactpoint over a series of iXed contacts to indicate the position of the signal; and the object of the invention is to provide such signal with an arm that will both automatically dispatch a signal or message to the train-dispatcher whenever the signal is thus displayed, and at the same time serve as a means to display the proper visual signal to an approaching train, thus showing that the telegraph-operator has displayed the necessary signal to arrest the train for the receipt of orders.

In the drawings which accompany this specication and form a part thereof, and in which Figure l is an elevation of a signal with my improvement in perspective, and Fig. 2 is` an enlarged plan view of my improvement detached, I show a railway-signal of known. construction,which is provided with the vertical rotating shaft A and the usual signals. B is a lever, by which the device is Aoperated from the room of the telegraph-operator. C is my attachment, by which a return-signal is automatieally sent to the train-dispatcher whenever the lever is operated. It simply consists of a number of Xed eontact-points and a contact-point secured to the lever, both being connected withthe telegraph-line insuchawaythat when the lever is moved across the xed contacts (as is necessary in operation) the circuit will be alternately opened and'closed, and thus automatically transmit a signal or message to the train-dispatcher. To prevent the operator from sending any like signal through the medium of the key, the signal given by the automatic device may be oi' such a natu're that it could not well be imitated with the key, or it might be inclosed and protected, so that the operator may not be aware of its nature.

While I have described my attachment in combination with a certain railway-signal, it is clear that it may be likewise used with equal advantage with other signal devices which are operated by hand for different purposes. y

In practice the railroad-operator, upon the receipt of a message from the train-dispatcher for a certain train, sets his signal, and the traindispatcher will receive anlautomatic signal,

which, from its peculiar nature, gives him indisputable notice that the operator has acted upon his orders.

I have shown co1itact-points that will transmit the word set7 to the dispatcher when the signal is set to indicate dangerf.7 Should the signal be reversed, the movement of the lever over the contact-points would transmit the same letters reversed, thus indicating that the signal had been reversed, and that it now indicates safety I am aware of English Patent No. 657 of 1879, and make no claim to the construction shown therein.

The combination of thevertical shaft A for operating a visual signal, the horizontal plate C, forming a step for the shaft, and carrying a series of fixed electrical contacts connected with a telegraplrline, and an arm carrying a contact-point and attached to said shaft, and eonstructedto both operate said shaft and signal and move said contact-point over the fixed contacts as the visual signal is moved, substantially as described.
